A key concern about counterfeits and weak intellectual property protection is that they may hamper innovation by displacing legitimate sales. This paper combines a natural policy experiment with randomized lab experiments to estimate the heterogeneous impacts of counterfeiting on the sales and...

Streaming music services have exploded in popularity in the past few years, variously raising optimism and concern about their impacts on recorded music revenue. On the one hand, streaming services allow sellers to engage in bundling with the promise of increasing revenues, profits, and consumer...

We study the impact of mandatory calorie posting on consumers' purchase decisions, using detailed data from Starbucks. We find that average calories per transaction falls by 6%. The effect is almost entirely related to changes in consumers' food choices--there is almost no change in purchases of...

We study the positive and normative effects of counterfeiting, i.e.,trademark infringement, in markets where consumers are not deceived by forgeries.The fact that consumers are willing to pay more for counterfeits than for generic merchandise of similar quality suggests that they value the...

Using a unique panel dataset and a new model, this article investigates the dynamic effects of counterfeit sales on authentic-product price dynamics. We propose a Bayesian random-changepoint simultaneous equation model that simultaneously takes into account three important features in empirical...

In this paper, we untangle the searchable and experiential dimensions of quality responses to entry by counterfeiters in emerging markets with weak intellectual property rights. Our theoretical framework analyzes the market equilibria under competition with non-deceptive counterfeiting and...

This paper develops a new method for estimating trends in the size of counterfeit markets. The method draws on principles of microeconomic theory and uses aggregated product-level data to estimate counterfeiting activities in various geographic markets. Using confidential firm unit forecasts and...

Following the Global Pharma Health Fund e.V. Minilab® protocol, we find 9.88% of samples have less than 80% of the correct active ingredient and 41.5% of these failures are counterfeits. Both product registration and chain affiliation of retailers are strong indicators of higher probability to...

In this paper I provide a theory for brand-protection strategies to reduce counterfeiting under weak intellectual property rights. My theoretical framework has general implications for endogenous sunk cost investments as a means of deterring counterfeiters. My model incorporates two layers of...

Focusing on 8 drug types on the WHO-approved medicine list, we constructed an original dataset of 899 drug samples from 17 low- and median-income countries and tested them for visual appearance, disintegration, and analyzed their ingredients by chromatography and spectrometry. Fifteen percent of...
